Abstract
Abstract Hydrogels for electronic applications require stretchability, high electrical conductivity, and high mechanical strength. A mechanically robust ionic conductive gelatin hydrogel is constructed by a simple soaking–heating process in an ammonium sulfate solution. Due to the combined effect of the salt‐out effect and heating, a gelatin hydrogel with large chain‐dense and ion‐rich regions is successfully constructed. This gel exhibits high ionic conductivity and high mechanical strength.
